HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 363,747, dated May 24, 1857. Application filed December 9, 1886. Serial No. 221,115. (No model.)

T0 at whom it may concern.-

Be it known that I, J AMES A. IRoNs, of Water Cure, inthe county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Utilizing \Vaste Heat in Buildings; and I do hereby declare that thefollowing isa full, clear, and eXact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to apparatus for heating upper stories of buildings and furnishing them with means for warming or cooking victuals; and it has for its object to utilize the heat from the stoves or fire-places used in the lower rooms by diverting the heat in the chimney into suitable drums or warmingovens; and with this object in view it consists in the improved construction, arrangement, and combination of parts hereinafter described, and afterward specifically pointed out in the claims.

In the drawings, Figure 1 is a vertical section from front to rear through a portion of two stories of a house, through the fireplace and grate in the lower story, the chimney, and the drum and oven in the upper story; and Fig. 2 is a vertical section on a plane at right angles to that of Fig: 1 through the walls and the warming apparatusin the upper story, the ,front of the chimney being partly broken away to show the interior. Fig. 3 is a section taken on line 3 3 Fig. 1.

Likeletters of reference mark the same parts in all the figures.

Referring to the drawings by letter, A is the lower floor, and B the upper floor, of ahouse, 0 being the chimney. There may be provided in the lower room a grate, as at D, or any proper stove or heater whose products of combustion pass into the chimney O, as shown. Through an opening in the chimney passes a sheet-metal box, E, which entirely fills the fine, and has an opening, F, in its bottom and an opening, G, in its top, closed at will by a valve or damper, I-I. Projecting from the front of this box E is a funnel-shaped-tube, I, which at its outer end opens into a metal drum or heater, J, through which the products of combustion are caused to pass, it being provided with a suitable escape-pipe, K, opening into the chimney C over the box E. A ventilator, L, is inserted in the front wall of the chimney just above the point where the pipe Kenters it, by means of which all noxious vapors or gases which might arise from the drum or connections are carried into the chimney.

The drum J consists of a rear chamber, a, through which the products of combustion pass, a front chamber, 0, having a shelf, a, and door 0, which acts as an oven .to warm and keep warm articles of food, &c., and a tank, f, which rests partially in both these chambers and rests on the partition 9 between them, but preferably the tank is suspended from the top. The escape-pipe K passes through this tank, as shown.

, The valve or damper H is operated byarod, h, passing through the heater or drum J, and having a handle at the front to operate it.

The pipe K has in it an ordinary damper, k, and the tank f is provided with a suitable cook or faucet, Z.

a In operating my improved devices thepro ducts of combustion pass up through the chimney, and, being diverted by the valve H, which forms a flue-board, pass into and through the drum J, thence through pipe K into the cl1imney, and are thus utilized to heat the upper room by radiation from the drum, or by direct heat when natural gas is used as fuel, first removing the partition 9, and which heats the warmingoven and the water in the tank. \Vhen the valve is partially closed, as shown in Fig. 1, the products of combustion will be passed in part direct up the chimney and in part through the drum. \Vhen-the valve is at a horizontal position, all the heat passes through the drum, and when vertical all passes directly up the chimney, leaving the drum cool. The passage through the drum in either of the open positions of valve H may be retarded by the damper k in pipe K;

The construction of the drum as described is such that the tank is heated on its bottom and sides, and by contact with these parts and the pipe the whole body of water is quickly and thoroughly heated, thus forming a warm or hot top to the oven. By these devices the heat of a fire in a lower room is utilized and economized, so that the necessity for a fire in the upper room is entirely obviated and its occupants are enabled to keep food warm for any desired length of timea great desideratum for parties lodging in upper rooms when meals are served from outside restaurants, or

I when food for infants or invali ds must be kept in the room.

The partition 9 is removable for the purpose of adapting the heating-drum to the use of natural gas for heating, or coal, as the case may be. WVhen coal is used as fuel, the partition is inserted in the drum, and then the heat is by radiation; but when gas is used for fuel the partition g is removed, so that the heat is direct, and may pass from one story of the house to another until the heat is all utilized. M is the natural-gas-supply pipe.

It will be understood that when natural gas is supplied through the pipe M an incombustible substance will be put into the grate Dfor the purpose of spreading the heat.
